== History ==

+

==Friends of ENTS==

+

Many prospecting members love the ENTS concept and space, but simply don't have time to make full use of a membership. They still however want to keep up to date and be able to stop in from time to time and see what's going on. ENTS is happy to announce the Friends of ENTS membership.

After the kind donation of a 70'sish Coca-Cola Vending machine, we started tearing into it to get it working. While there were a few issues off the start, it's in good mechanical order and tests showed it's power consumption was >50% less than the existing smaller pop machine in the space.

+

==What are membership costs?==

+

'''Monthly''' memberships are $75 a month<br />

+

'''Starving Hacker''' memberships are available by request. Talk to a director.<br />

+

'''Yearly''' memberships are available for $750<br />

+

'''Friends of ENTS''' memberships are $10/25 a month<br />

+

There is no requirement for ongoing membership, should you need to suspend your membership, let the directors know when to suspend and resume your membership.

−

One major problem was that the coin mechanism would not accept newer loonies and toonies. A replacement mechanism would be $200 or more. A bit pricy for a starving hackerspace, so we are doing what all good hackers do, overengineer a solution with parts at hand. In this case, utilize the door RFID tags the members have anyways and use them to debit from a pre paid pop account.

+

==How to pay==

+

ENTS prefers that members pay their dues via recurring PayPal subscriptions, as it helps greatly with budgeting<br />

+

Members can however pay by single paypal payments, cash or cheque. <br />

+

ENTS does not offer an type of trading of labour, materials or tools for membership, sorry. <br />

Oricanus did much of the work to figure out the mechanics of the machine and how to bypass the coin mech to allow us to dispense product. It's actually very easy. On the connector to the coin mech, short pins 1-7 together (all the time) and then momentarily contact pins 1-3 and then make your selection.

== V1 ==

+

−

+

−

Version 1 is to basically setup the nessecary hardware to replace the coin mech and to use the RFID tags to debit from an account with little or no modification to the existing electro mechanical dispensing system. Various options were considered but parts on hand and flexibility came together in the following:

Current goals: Users provide cash or paypal to director who adds to account for thier tag via web interface or 'credit' tags on the pi.

+

−

+

−

On scan, Pi checks database for balance. If sufficient balance, deduct $1 and dispense product. If insufficent balance, then display an unhappy message . Once product is dispensed display the username and balance remaining for 15 seconds. When 'idle' the screen will goto a slide show of comical and ficticious beverages (Duff, Slurm, Nukacola, etc)
